Patented June 20, 1939 UNITED STATES PATENT OFFECE 1 Claim.

'Ihe present invention relates to an oil baiile designed for use on crankshafts in internal combustion engines in conjunction with the bearing connections therewith of the connecting rod and the object of the Ainvention is to prevent the throwing of the oil up into the upper portions' of the cylinders thereby diminishing oil consumption, decreasing the formation of carbon and the like.

Another important object of the invention resides in the provision of a device of this nature which is simple in its construction, inexpensive to manufacture, easy to install or incorporate in the construction of the engine, thoroughly ef cient and reliable in use and operation and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds,

the invention consists in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:-

Figure 1 is a sectional View through the crank portion of a crankshaft of an engine showing a bearing and a connecting rod thereon with an embodiment of my device incorporated with respect thereto.

Figure 2 is a sectional View taken substantially on the line 2-2 of Figure 1 looking downwardly.

Figure 3 is an end elevation of the embodiment.

Figure 4 is a View similar to Figure l showing another embodiment of the invention.

Figure 5 is a side elevation thereof.

Figure 6 is a bottom plan View of one part of the second embodiment.

Figure 7 is a View similar to Figures 1 and 4 showing the invention incorporated in the bear- 40 ing.

Figure 8 is a sectional View taken substantialiy on the line 8--8 of Figure 7.

Referring to the drawings in detail and now particularly to the first embodiment shown in 45 Figures 1, 2, and 3, it will be seen that the numeral 5 denotes the crank of a crankshaft, nu-

meral 6 the connecting rod and numeral i the bearing associated between the two in the usual well known manner. Numerals 8 denote bolts holding the segments of the bearing together. The parts thus far described are conventional.

Now referring particularly to the first embodiment of my invention it will be seen that I have an varcuate body S of sheet metal or the like with an elongated intermediately disposed slot lil formed therein and the end portions formed with co-planar oppositely extending ears Ii apertured to be received by the bolts 8 to hold the body about the upper portion of the bearing l. On the marginal edges of the body 9 are formed flanges i4 which are arcuate in cross section and being bowed upwardly will tend to deflect the oil downwardly from the upper portion of the cylinder in which the connecting rod operates.

In Figures 4, 5 and 6, I have shown another embodiment of my invention wherein flanges I4' have earsI Il' to be received in overlapping relationship in engagement with the bolts' In Figures 7 and 8 I have disclosed the same idea incorporated in the bearing iii the flanges l5 of which are provided with annular outwardly directed deflecting portions il.

It is thought that the construction, operation, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacricing any of its advantages,

What is claimed is:

An oil deflector device of the classy described including an arcuate sheet metal body having an elongated intermediate slot, ears struck outwardly from the ends thereof in co-planar relationship to one another, and flanges formed on the marginal edges of the body, said anges being bowed upwardly and arcuate in cross-section.
